My G4’s internal drive had serious errors that Disk First Aid couldn’t fix which sometimes made it freeze at startup. If I start it up in single user or verbose mode, I see fsck hanging while attempting to repair.
Using Carbon Copy Cloner, I backed up the entire drive to my LaCie external, erased the internal drive, and restored it.
It’s running nice and fast now. After running for a few years, it’s a good way to get rid of all of the fragmentation.
What disk utility are most people using now? I haven’t trusted Norton Utilities since their HFS+ fiasco, so I guess the choice is between Drive 10 & TechTools Pro.
